Studies on the male and female copulatory apparatus of Trichuris globulosa (Nematoda, Trichuridae)

Pubblicato online: 01 Dec 2007
Pagine: 151 - 156

Astratto

Abstract

The process of copulation in Trichuris globulosa (see Linstow, 1901) Ransom, 1911 has been studied using morphological, histological and scanning electron microscopical techniques (Keilley et al., 1973). The ventral coiling of the posterior part of the male body around the female is achieved by specialized muscles of the ventral body-wall. The single simple pointed spicule emerges with the everting cirrus and acquires a J-shape. The spicule may help in keeping apart the cuticular brim of the non-spiny noneversible part of the vagina during insemination. The cloacal tube is long with a detached internal cuticle which is eversible to the outside as a cirrus. Eversion is brought about by the protrusion of the spicule and contraction of the muscles of the spicule pouch. During eversion part of the proximal cloacal tube is also extruded and forms the globular part of the cirrus. The globular part is covered with spines, which may help in retaining the male and female in copula. The vagina is differentiated into the proximal vagina uterine and distal vagina vera. The vagina vera has a distal eversible spiny part and a proximal noneversible unarmed part. In Trichuris globulosa, the vagina vera is shorter than the spicule.

Liver cystic echinococcosis in humans — a study of 30 cases

Pubblicato online: 01 Dec 2007
Pagine: 157 - 161

Astratto

Abstract

The aim of this study is to demonstrate the clinical manifestations and diagnostic approach to liver hydatid disease and suggest its treatment. The prospective study was carried out on 30 patients with liver hydatidosis. Hepatologic examinations were based on: medical history, physical examination, biochemical and serological tests, ultrasonography and computed tomography scanning. Twenty-five (83.3 %) patients underwent radical cyst resection, while in 5 (16.7 %) cases liver resection with left lobectomy was also performed. Hydatid cyst was histopathologically verified in all the patients. Our results showed that the patients with multiple cysts had impaired functional liver tests significantly more often than patients with unilocular cyst. In addition, ultrasonography and computed tomography scans are the valid imaging procedures in diagnosis. Radical, surgical resection of hepatic hydatid cysts is the goal of treatment.

Abstract

Light and scanning electron microscopical examination and molecular analysis of pinworm samples collected from the Sumatran orangutan (Pongo abelii) from Sumatra (Indonesia) revealed the presence of a new taxon, Pongobius hugoti gen. et sp. n. (Oxyuridae: Enterobiinae). The monotypic genus Pongobius is characterised by the presence of a triangular mouth, three rounded teeth and three chisel-like inner teeth in the buccal cavity, an oesophagus with a long pharyngeal part, corpus posteriorly slightly enlarged and continuing as a pyriform bulb, isthmus absent. These features differentiate P. hugoti from all members of the subfamily Enterobiinae. The male has a long caudal appendix (> 50% of total tail length). Molecular analysis of the new taxon is presented for more precise identification.

Prevalence of important zoonotic parasites in dog populations from the Slovak Republic

Pubblicato online: 01 Dec 2007
Pagine: 170 - 176

Astratto

Abstract

Dogs serve as the vectors of serious parasitic diseases with a zoonotic character. In a one-year-study, we collected and examined 752 faeces of dogs. In these faecal samples, 11 different species of intestinal endoparasites were detected, as follows: Toxocara spp. eggs (21.9 %), eggs from the family Ancylostomatidae (18.4 %), coccidia oocysts (10.4 %), eggs of Trichuris spp. (10.0 %), Toxascaris leonina (7.3 %), Capillaria spp. (5.9 %), Taenia type eggs (3.2 %) and Giardia spp. cysts (1.6 %). Echinococcus multilocularis was detected in one sample. Toxocara spp. eggs were dominant in all dog categories, but in hunting dogs they occurred at the highest rate (45.1 %). Faecal samples of dogs from rural ecosystems showed 66.0 % prevalence of intestinal helminths. Presence of Toxocara spp. eggs was found in 25.0 % of sand samples.

Abstract

We conducted a survey of the presence, prevalence and diversity of gastrointestinal helminths in faecal samples and stomach contents of three turtle species, — Erymnochelys madagascariensis (Chelonia: Podocnemididae), Pelomedusa subrufa and Pelusios castanoides (Chelonia: Pelomedusidae), — from several localities in Madagascar. Four nematode species were detected: Atractis chabaudi, Camallanus chelonius, Falcaustra pelusios, and Spiroxys sp. E. madagascariensis, with all four species, had the greatest helminth diversity. A. chabaudi was the community’s core species, whereas Spiroxys sp. was a satellite species. Only two species (A. chabaudi and Spiroxys sp.) were found in P. subrufa and only one, Spiroxys sp., in P. castanoides. These are the first helminthological data on E. madagascariensis, one of the most threatened freshwater turtles in the world.

Abstract

Specimens of the fishes Scarus ghobban Forsskål (Scaridae) and Crenimugil crenilabis Forsskål (Mugilidae) were caught in the Red Sea off the coast of Sharm El-Sheikh, South Sinai, Egypt. Ten (20 %) and 15 (50 %) of these fishes, respectively, were found to harbour intestinal trematodes. Scarus ghobban was parasitised by Prosteganoderma brayi gen. nov., sp. nov. (Zoogonidae) and C. crenilabis by Forticulcita mugilis sp. nov. (Haploporidae). Prosteganoderma gen. nov. is similar to Steganoderma Stafford, 1904, but clearly differs from it and from all the other genera of the subfamily Lepidophyllinae Stossich, 1903 in having a large ventral sucker surrounded by a large prominent fleshy fold of the body wall and a pre-testicular uterus. Forticulcita mugilis sp. nov. is similar to F. glabra Overstreet, 1982, the type and the only species of the genus, but clearly differs in having a larger body size, a longer forebody, an intestinal bifurcation in the middle of the body, subequal gonads, Laurer’s canal opening dorsally at a considerable distance posterior to the testis and a much larger egg size.

Species richness, diversity and specificity of the parasites of bream Abramis brama (L.) and perch Perca fluviatilis L. in the estuary of the Odra River, Poland

Pubblicato online: 01 Dec 2007
Pagine: 188 - 192

Astratto

Abstract

The parasitological studies were carried out on bream and perch from brackish water of Pomeranian Bay and the Szczecin Lagoon — a mouth of the Odra River. Bream and perch hosted 21 and 13 parasitic species, respectively. The species richness and diversity of parasites were much higher for bream and the abundance of parasites in bream was nearly four-fold higher than that in perch. Faunistic similarity of both parasite communities was low. The dominant group of parasites in both fish hosts was digeneans. Five species were specialists of bream, while only one species was a perch specialist. Five new host records have been reported in Poland for the following species: Myxobolus dispar, Hysterothylacium aduncum, Khawia sinensis, Echinorhynchus gadi and Pomphorhynchus laevis.

Soil nematode community structure in a Chinese sand dune system

Pubblicato online: 01 Dec 2007
Pagine: 204 - 209

Astratto

Abstract

Soil nematode community structure was studied in a terrestrial sand dune system of the Horqin Sandy Land, Northeast China. The nematode abundance and generic composition in four sites (from the lowland, the middle part of windward slope and the top of windward slope to leeward slope) and three soil layers (0–20 cm, 20–40 cm and 40–60 cm) of the stabilized sand dune were compared. The results showed the total number of nematodes which ranged from 11 to 160 individuals per 100 g dry soils was significantly different among the sites and the depths (P < 0.05). Thirty genera were observed and Acrobeles was the dominant genus in our investigation. A significant difference in the abundance of bacterivores was found among the depths (P < 0.01). The total numbers of nematodes and plant parasites positively correlated with electronic conductivity, soil moisture, total organic carbon and nitrogen contents (P < 0.05). S, TD, NCR and PPI were found to be sensitive to environmental stress in the stabilized sand dune system.

Abstract

A total of 40 carp bream, Abramis brama (L.) from Lake Jamno were examined for their parasites in May 2002. Lake Jamno is a brackish-water coastal lagoon, strongly eutrophied and polluted by communal and industrial sewage from the city of Koszalin. The survey yielded 15 parasite species, representing different systematic groups, including 7 monogeneans Dactylogyrus auriculatus, D. falcatus, D. wunderi, D. zandti, Gyrodactylus elegans, Gyrodactylus sp., Diplozoon paradoxum; 4 digeneans (at the stage of metacercaria) Diplostomum sp., Tylodelphys clavata, Ichthyocotylurus platycephalus, I. variegatus; 1 cestode Caryophyllaeus laticeps; 2 crustaceans Ergasilus sieboldi, Argulus foliaceus; and 1 hirudinean Caspiobdella fadejewi. Monogeneans constituted the most abundant parasite group, accounting for 61.5 % of all parasite individuals collected. They were followed by the cestodes (20.7 %), digenean flukes (16 %), crustaceans (0.7 %), and leeches (0.2 %).

Abstract

Specimens of the fishes Scarus ghobban Forsskål (Scaridae) and Crenimugil crenilabis Forsskål (Mugilidae) were caught in the Red Sea off the coast of Sharm El-Sheikh, South Sinai, Egypt. Ten (20 %) and 15 (50 %) of these fishes, respectively, were found to harbour intestinal trematodes. Scarus ghobban was parasitised by Prosteganoderma brayi gen. nov., sp. nov. (Zoogonidae) and C. crenilabis by Forticulcita mugilis sp. nov. (Haploporidae). Prosteganoderma gen. nov. is similar to Steganoderma Stafford, 1904, but clearly differs from it and from all the other genera of the subfamily Lepidophyllinae Stossich, 1903 in having a large ventral sucker surrounded by a large prominent fleshy fold of the body wall and a pre-testicular uterus. Forticulcita mugilis sp. nov. is similar to F. glabra Overstreet, 1982, the type and the only species of the genus, but clearly differs in having a larger body size, a longer forebody, an intestinal bifurcation in the middle of the body, subequal gonads, Laurer’s canal opening dorsally at a considerable distance posterior to the testis and a much larger egg size.

Species richness, diversity and specificity of the parasites of bream Abramis brama (L.) and perch Perca fluviatilis L. in the estuary of the Odra River, Poland

Pubblicato online: 01 Dec 2007
Pagine: 188 - 192

Astratto

Abstract

The parasitological studies were carried out on bream and perch from brackish water of Pomeranian Bay and the Szczecin Lagoon — a mouth of the Odra River. Bream and perch hosted 21 and 13 parasitic species, respectively. The species richness and diversity of parasites were much higher for bream and the abundance of parasites in bream was nearly four-fold higher than that in perch. Faunistic similarity of both parasite communities was low. The dominant group of parasites in both fish hosts was digeneans. Five species were specialists of bream, while only one species was a perch specialist. Five new host records have been reported in Poland for the following species: Myxobolus dispar, Hysterothylacium aduncum, Khawia sinensis, Echinorhynchus gadi and Pomphorhynchus laevis.

Soil nematode community structure in a Chinese sand dune system

Pubblicato online: 01 Dec 2007
Pagine: 204 - 209

Astratto

Abstract

Soil nematode community structure was studied in a terrestrial sand dune system of the Horqin Sandy Land, Northeast China. The nematode abundance and generic composition in four sites (from the lowland, the middle part of windward slope and the top of windward slope to leeward slope) and three soil layers (0–20 cm, 20–40 cm and 40–60 cm) of the stabilized sand dune were compared. The results showed the total number of nematodes which ranged from 11 to 160 individuals per 100 g dry soils was significantly different among the sites and the depths (P < 0.05). Thirty genera were observed and Acrobeles was the dominant genus in our investigation. A significant difference in the abundance of bacterivores was found among the depths (P < 0.01). The total numbers of nematodes and plant parasites positively correlated with electronic conductivity, soil moisture, total organic carbon and nitrogen contents (P < 0.05). S, TD, NCR and PPI were found to be sensitive to environmental stress in the stabilized sand dune system.

Abstract

A population of Longidorus distinctus Lamberti, Choleva & Agostinelli, 1983 was recovered from soil samples collected from the rhizosphere of plum trees at Král’ovský Chlmec in south-eastern Slovakia. The area is characterized by sandy soil derived from dune sand. The population comprised females, juveniles of four developmental stages and a bisexual specimen. No males were found. It is the first record of this species from Slovakia. Two females were sequenced and the sequence was deposited in Gen-Bank.

Abstract

The presence of metacercariae of Centrocestus formosanus was detected on the gills of goldfish (Carassius auratus L.) imported from Singapore and obtained from two pet shops. This is the first report of the parasite in Croatia. The histopathological changes observed lead to the conclusion that the infection could be one of the reasons for the death of goldfish.

Parasites of carp bream, Abramis brama, from Lake Jamno, Poland

Pubblicato online: 01 Dec 2007
Pagine: 222 - 225

Astratto

Abstract

A total of 40 carp bream, Abramis brama (L.) from Lake Jamno were examined for their parasites in May 2002. Lake Jamno is a brackish-water coastal lagoon, strongly eutrophied and polluted by communal and industrial sewage from the city of Koszalin. The survey yielded 15 parasite species, representing different systematic groups, including 7 monogeneans Dactylogyrus auriculatus, D. falcatus, D. wunderi, D. zandti, Gyrodactylus elegans, Gyrodactylus sp., Diplozoon paradoxum; 4 digeneans (at the stage of metacercaria) Diplostomum sp., Tylodelphys clavata, Ichthyocotylurus platycephalus, I. variegatus; 1 cestode Caryophyllaeus laticeps; 2 crustaceans Ergasilus sieboldi, Argulus foliaceus; and 1 hirudinean Caspiobdella fadejewi. Monogeneans constituted the most abundant parasite group, accounting for 61.5 % of all parasite individuals collected. They were followed by the cestodes (20.7 %), digenean flukes (16 %), crustaceans (0.7 %), and leeches (0.2 %).
